Trane BRG1207 1-1/4" Bearing Assembly

Thermostatic expansion valves are an integral part of your refrigeration unit. They are responsible for ensuring the right dosage of refrigerant is entering the cooling coil to ensure maximum efficiency in the air conditioning of the system.    These special expansion valves come with a temperature sensor that is mounted at the end of the evaporator coil. They incorporate signals from this sensor to maintain the required temperature of the HVAC system. The thermostatic expansion valve works like a precision device that can regulate the measurements of the liquid refrigerant that flows into the evaporator of your system. This regulation in the flow of the refrigerant is essential to prevent the reverse flow of the refrigerant into the compressor of your system.    Through this mechanism, the thermostatic expansion valve successfully separates the high and low pressure sides of the refrigeration/air conditioning system. The liquid refrigerant enters the expansion ...

Inspect the bearing assembly regularly for excessive vibration, unusual noise, overheating, or lubricant contamination during blower operation. Ensure the shaft alignment and mounting hardware remain secure to prevent uneven wear. Periodically lubricate the bearing if applicable and keep surrounding components free from dust and debris buildup.

• Excessive bearing noise due to wear or lack of lubrication.
• Overheating from friction or misalignment.
• Shaft play or looseness causing vibration.
• Premature failure from contamination or improper installation.
• Bearing seizure under heavy load conditions.
